ORRIN MILO WHITMAN, OF BOSTON, MASSACHUSETTS.

DOOR-SECURER.

SPECIFICATION forming part of Letters Patent No. 371,650, dated October 18, 1887.

Application filed February 21, 1887. Serial No. 228,334. (No model.)

To all whom it may concern:

Be it known that I, ORRIN MILO WHIT- trim, of Boston, in the county of Suffolk, of the Commonwealth of Massachusetts, have invented a new and useful Improvementin Door- Fasteners; and I do hereby declare the same to be described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is a-front elevation, and Fig. 2 a transverse section, of part of a door and its casing with my improved fastening applied thereto, the nature of it being defined in the claim hereinafter presented. Fig. 3 is a front elevation, and Fig. 4. a side view, of a modification in shape of that part of my invention which operates with the plate D and its curved horn or projection, as hereinafter de scribed.

In the said drawings, A denotes the door, and B the casing, the connections of them being hinges O, as represented.

D is a base-plate, fastened to the casing and provided with a horn or curved projection, E, formed and extending from it as indicated. F is another such base-plate, secured to the door and provided with a slotted or bowshaped handle, G,formed as shown, andjointed or hinged to such base-plate.

On turning the handle upon the projection E the inner end or part, b, of the slot at of such handle will be borne against the inner curved face or portion, a d, of such projection, and in advancing thereon will cause the door to be pressed rearwardly and inwardly, so as to be firmly closed in the recess of the casing.

The curve of the bearing part c d of the inner edge of the horn or projection E is not the arc of a circle whose center is at the axis of the joint of the handle G, (such are being shown in Fig. 2 at e by dotted lines,) but is angular thereto, so as to cause the door, while the handle is being moved against such bearing part, to be forced rearwardlythat is, in a direction toward the part of the casing to which the door is hingedsuch a movement of the door being to keep it from sticking at its front edge against the casing. In refrigerators, owing to the dampness generated or changes of temperature, the doors are liable to swell and frequently to stick fast in the easing. WVith my improved fastening applied to a door and its casing such sticking of the door cannot easily occur. The door by means of it can be tightly closed, and can be easily opened or closed, as occasion may require. The baseplates D and F have countersunk holes in them to receive the screws 8, used in fastening such base-plates, one to the door and the other to the casing.

Instead of slotting the handle and having the curved horn to go through it when the handle is turned against such horn, I form the handle with a cylindrical projection, f, (see Figs. 3 and 4,) at its lower part, which I arrange eccentrically to the joint-pin of such handle.

\Vhen the handle is turned down, the eccentric bears against the horn and acts with it to produce results such as are above described as incident to the slotted handle. The handle formed or provided with the eccentric may be considered as a mechanical equivalent for the handle as made-with the slot to receive and act against the horn.

I do not claim a doorfastener constructed and applied in manner and to operate like that described in the United States Patent No. 332,495, the handle in such door-fastener being movable in a vertical plane in order to press the doorlaterally, whereas with my door-fastener the handle is movable horizontally, and the door is by the fastener moved toward that part of the casing to which the door is hinged, such being to prevent sliding of the doorin the opposite part of the casing. In my fastening .there is nolug projecting laterally from a head having an eccentric axis, nor is there any keeper or catch formed with an opening or notch to receive such lug, as is the case in such patented fastening shown in said Patent No. 332,495;

I claim- The door-fastener,substantially as described, composed of the base-plate D, its curved horn or proj ection E, the base-plate F, and the slotted handle G, such handle being hinged to such base-plate F, and all being arranged and constructed and for use essentially as set forth.

ORRIN MILO WHITMAN.
